claims. (cl. 18s-7s) The presentapplication relates to an improved light xture and moreparticularly relates to an improved frame and door assemblyffor flush mounted ceiling lights.

It is an objectof the present invention to provide an improved frame and door assembly of the above mentioned type which is simple in construction, economical of manufacture -and f reliable and effi-cient in operation. y

A further object of the invention is to provide an improved assembly of the above mentioned type including an improved clip for mounting the glass member in the door which clip also functions to prevent undesirable esescape of light through the door frame.

Another object of the invention is to provide an improved clip for mounting the glass member in the door frame, which clip also serves to reinforce the corners of the door frame.

It is also an object of the invention to provide an assembly of the above mentioned type including improved means for mounting the door within the xed frame which means permits an improved yclose iit between the door frame and the fixed frame.

` -Other and more detailed objects of the nvention will become apparent from a consideration of the following speCiCatiOn, the appended claims and the accompanying drawing, wherein:`

Fig. 5 is a View in perspective ofthe clip employed in the construction illustrated in Figs. 1, 2, 3' and 4.

It will be appreciated from a complete understanding of the present invention that the improvements thereof may be readily embodied in equipment of widely different types anddesigns. In an illustrative but not a limited sense, 'the improvements of the present inv-ention'are hereillustrated and described as embodied ina frame and door assembly for a liush mounted ceiling light. It will also be appreciated that the term ceiling lightirefers broadly to the type of light conventionally mounted in ceilings but which, of course, may be also readily mounted in walls or any other similar surface.

. 2 Referring to the drawing, the assembly of the present invention generally comprises a fixed frame I0 adapted to be flush mounted in a ceiling I2, a door frame I4 pivotally mounted in the xed frame I0; a glassy member I6 and a plurality of clips I8 mounting the glass ymember I6 in the door frame I4.

In the preferred embodiment illustrated in the drawing, the fixed frame I0 is square and defines alarge square Vopening Zl. The frame I0 is shaped to define a square recess 22 in its lower face, as viewed in Figs. l and .2. Adjacent one side of this recess the adjacent'walls of the recess are provided with slots 24 extending at right angles to the adjacent. recess-wall and disposed adjacent the cuteror lower face of the frame I0 as viewed in Figs. l and 2.

The door frame I4 is also square and adapted to closely fit within the recess 22. The frame I4 in the embodiment illustrated is formed of a single strip of sheet metal, which in cross section is similar to conventional angle iron and includes vflanges 26 and 28. The frame I4 is formed by bending the fiange-28 to define the four outer walls ofthe square frame I4 and mitering the ange 26 adjacent the bends in the flange 23 so that the adjacent mitered edges 3U and 32 of the flange 25 are disposed substantially in abutting engagement whenthe frame I4 is in its nished shape. The ends ofthe strip from which the frame I4 is formed are secured together by spot welding overlapping end portions of the flange 28. v The door frame I4 is pivotally mounted on the frame I0 by means of rivets 34 extending through the slots '24provided in the frame.l I0 and extending through circular apertures, 3S provided in the ange 28 of the .frame `vI4 and adapted to register with the slots 24 when the door frame I4 is received in the-recess 22 with the outer surface of itsflange- 26 ldisposed subev stantially flush with the outer surface o the frame I0. The rivets 34 serve as pivot pins, permitting the door` frame I4 Ato be moved pivotally relative to the fixed frame I0 and are also adapted to slide longitudinally of the slots 24 to permit the doorto be moved bodily relative to the frame I0 as soon as the doory has been opened slightly.V By virtue of the bodily movement thus permitted, inter-ference between the frame I4 and the frame` I0 is prevented,` even though kthe yframe I4 is proportioned to closely 'fit vthefrecess 22 in tl'ieiram'eII).` 1 if The clip I Blof thepreferred embodiment' illustrated in the drawing is stamped from al yfiat strip of sheet metal. As best illustrated in Fig.

5, spaced portions 38 of the clip are turned upwardly to provide flanges disposed in perpendicular planes. These flanges are integrally interconnected by a fiat web or intermediate portion 40. The clip also includes a pair of spaced finger portions 42 integral with the iiange portions 38 and disposed in the plane of the intermediate portion 49 and extending at right angles to each other. In use, the clip, in the shape just described, is placed in one of the corners of the door frame I4 with the flanges 38 overlying portions of the flange 28 of the frame I4 to which they are spot welded or otherwise suitably secured, and with the intermediate portion 40 in engagement with the ange 2G of the frame I4 and overlying the abutting mitered edges 30 and 32 as best illustrated in Fig. 3. It will now be appreciated that in this position, the intermediate portion 40 of the clip serves to prevent `the passage of light between the abutting mitered edges of theflange 26; Asl is clearly illustrated, the. flanges 38 engage and are securedv to the flange 28 of the framer I4- in spaced relation to the corner-of the frame, thus avoiding interference with the rivets 34 in` the corners of the frame I4 in which the rivets are mounted. After the Iianges 38 have been secured to the frame I4, the finger portions-42 are deformed upwardly by bending them along the lines indicated in Fig. in broken lines at 44. The glass member I6 is then placed in the frame I4, fitting inside of the finger portions 42 of theclips at each corner of the frame and then finger portions 42 are bent inwardly along the lines indicated at 46 in'broken lines in Fig. 5, to the position illustrated in Figs. 2, 3 and 4, andy illustrated in broken lines in Fig; 5. In this position, as illustrated in Fig. 2, the outer end portion of the fingers. 42 beyond the fold line 46 overlies the marginal portion of the inner face of the glass member I6 to securely hold the latterin place. As illustrated in Fig. 2, the outer face of the glass member I6, at each of its corners, engages the intermediate portion 40 of the clip I8, the glass member I6. thus beingA entirely supported bytheclips I8.

In the embodiment illustrated in the drawing, the 'door frame I4 may be secured in the closed positionv illustrated in the drawingby 'a member 48 extending throughV an aperture provided in the frame I4 and having a threaded engagement (not illustrated) at its inner endwith the fixed frameA I0, and havingv a knurled portion on its outer-end for facilitating rotation thereof` While only one specific embodiment of the invention has been illustrated. and described in detail herein, it will bereadily appreciated that numerous modifications.. and changes may be made thereinwithout departing fromthe spirit ofthe present invention.
